282 BIOLOGICAL SURVEY OF 



TiPULiDAE. The Crane Flies 



TiPULINAE 



In 1926 Dr. C. P. Alexander of Amherst, Mass., visited the 

 Island, stopping at Southwest Harbor, and found it ^'certainly 

 one of the richest and most remarkable faunas anywhere in 

 the world." For that reason, most careful collecting has 

 been done in this family, and Doctor Alexander and our friend, 

 Mr. Walter H. Harrison, the botanist, have made trips to the 

 Island for a few days during the past three years. They 

 Doctor Brower, and the writer, have collected together and 

 separately, and while the 197 species fall short of our goal 

 of 200, there is no doubt that the elusive three species, as 

 well as others, will be found by the time the supplement to 

 this list is published. We have had some of our happiest days 

 in this search, which we shall continue. The letter (J) is 

 for Johnson, and the other three are represented by their 

 initials. 



In the Occasional Papers of the Boston Society of Natural 

 History, Vol. V, pp. 223-231, January 12, 1937, being part 

 of the second Supplementary List, Doctor Alexander gives 

 many records of species taken on the Island. To combine 

 them with the list below would be confusing, and reference is 

 therefore made to this paper, particularly because Doctor 

 Alexander discusses some of the habitats, which should be 

 read in connection with the listed species. 



Tanyptera Latreille
